KETERKAITAN STRUKTUR KOMUNITAS MEIOFAUNA DENGAN KERAPATAN LAMUN DAN PARAMETER LINGKUNGAN DI SELAT DOMPAK, KEPULALIAN RIAU
Abstract: A study on the
relationship between meiofauna community structure with seagrassdensity and
environmental parameters has been carried out in the Dompak Straitwaters, Riau
Archipelago. This study were investigated on four different seasonsthroughout a
year, from May 2005 to April 2006. Three sampling site, i.e.., Al, A2and A3
were chosen to represent research sites. The sediment samples were tekenby PVC
cores, in which six layers were separated (i.e. 0-5 cm, 5-10 cm, 10-15 cm,15-20
cm, 20-25 cm and 25-30 cm). The environmental parameters, such ascurrent
velocity, the sediment composition, total organic carbon (TOO, totalorganic
matter (TOM), pH and redox potential (Eh), were also observed. The dataon
meiofauna, seagrass density and environmental parameters were
analyzedstatistically by a regression analyisis. This analysis was run using a
SPSS softwareversion 11.5 for Windows. The meiofauna was dominated by
Nematodes,Copepods, Polychaetes, Foraniiniferans and Turbellarians. The results
areshowing that the meiofaunal community structure would depend on
severalconditions such as seagrass density, environmental factors and
hydrologicalcharacteristics. The regression results are showing that the
meiofaunal communitystructure patterns was significantly correlated with
seagrass density and to theenvironmental parameters. Vertically, the meiofaunal
community structurepatterns seems to be more affected by TOC and TOM. While the
horizontally, itseems to he more affected by current velocity, TOM and pH.
